The News That Matters about the Nuclear Industry

Failure of Japan’s 20 year, costly, nuclear reprocessing project

en-433551-thumbx300-monjuCostly Japanese prototype nuclear reactor shuts down  http://eandt.theiet.org/content/articles/2016/09/costly-japanese-prototype-nuclear-reactor-shuts-down/ By Jack Loughran, September 21, 2016

The Monju nuclear reactor in Japan, which has operated for less than a year in more than two decades at a cost of 1tn yen (£7.6bn), is set to be scrapped. The prototype fast-breeder reactor was designed to burn plutonium from spent fuel at conventional reactors to create more fuel than it consumes.

The process is appealing to a country whose limited resources force it to rely on imports for virtually all its oil and gas needs.

But Tokyo believes it would be difficult to gain public support to spend several hundred billion yen to upgrade the Monju facility, which has been plagued by accidents, missteps and falsification of documents.

There is also a strong anti-nuclear sentiment in Japan in reaction to the 2011 Fukushima atomic disaster, and calls to decommission Monju have been growing in the ruling Liberal Democratic Party, with scant results from using around 20 billion yen of public money a year for maintenance alone.

Science Minister Hirokazu Matsuno, Trade Minister Hiroshige Seko and others had decided to shift policy away from developing Monju, a fast-breeder nuclear reactor in the west of the country, the government said.

They had also agreed to keep the nuclear fuel cycle intact and would set up a committee to decide a policy for future fast-breeder development by the end of the year.

A formal decision to decommission Monju is likely to be made by the end of the year, government officials said.

The decision would have no impact on Japan’s nuclear recycling policy as Tokyo would continue to co-develop a fast-breeder demonstration reactor that has been proposed in France, while research will continue at another experimental fast-breeder reactor, Joyo, which was a predecessor of Monju.

“The move will not have an impact on nuclear fuel balance or nuclear fuel cycle technology development or Japan’s international cooperation,” said Tomoko Murakami, nuclear energy manager at the country’s Institute of Energy Economics.

Before the Fukushima disaster, Japan had planned to build a commercial fast-breeder before 2050, but according to the International Energy Agency that project may be delayed, given the difficulties at Monju.

The fallout from the Fukushima disaster is continuing. Specialised robots have been developed to retrieve some of the radioactive material from the ill-fated plant but they have been repeatedly unable to complete their task because the high levels of radiation destroys their circuitry.

Nuclear reprocessing a failure as a method of dealing with radioactive wastes

Where will SA put lethal nuclear waste?, BD Live, BY NEIL OVERY  SEPTEMBER 20 2016, “……THE UK’s Thorp reprocessing plant, built at great cost in the 1990s, is due to close in 2018, leaving a decommissioning nightmare estimated to take at least 100 years to complete, at huge cost. In Japan, the Rokkasho reprocessing plant, which was due to open in 2008 at a cost of R100bn, has yet to open and has so far cost nearly R400bn over a 26-year period.

France, the only country that reprocesses nuclear fuel on a significant scale, has only been able to do so because of a huge subsidy from the state-owned energy company, EDF.

Despite initial hopes, a large quantity of highly radioactive waste that still needs disposing remains after processing. There are also serious security considerations, because reprocessing high-level waste results in the creation of separated plutonium, which could be stolen and worked into a simple, dirty bomb. The very existence of separated plutonium eases nuclear proliferation.

Nuclear proponents often champion so-called “fast reactors” as a different form of reprocessing that could solve the waste problem. These reactors are designed to burn more plutonium than they breed.

But after 50 years of research and vast expense, not one has operated commercially due to the high costs associated with running them and the fact that they still produce significant quantities of high-level waste that needs disposal. Due to these chronic limitations, most have closed down.

The Kalkar fast reactor in Germany, which cost R100bn to build, never operated and was sold at a huge loss in 1995 and converted into an amusement park.

The US National Academy of Sciences stated in 2008 that the reprocessing of nuclear fuel makes nuclear energy “more expensive, more proliferation-prone and more controversial”……

The US has tried, and after spending the equivalent of R1.4-trillion, has given up. In 2002, Yucca Mountain in Nevada was identified as the site for an underground repository for high-level waste. Despite tens of thousands of pages of scientific research and countless investigations, no agreement has been reached about whether it is safe to store high-level nuclear waste underground. The site was closed in 2011 by the Obama administration.

In Onkalo, Finland, a R75bn underground repository is being built, despite significant opposition.

Similar options are being considered in the UK, France and Sweden.

No one knows, however, if waste can be stored safely underground for tens of thousands of years…….. http://www.bdlive.co.za/opinion/2016/09/20/where-will-sa-put-lethal-nuclear-waste

America giving up on the Mixed Oxide Nuclear Fuel (MOX) boondoggle

“The first question I asked was why if she mistakenly skipped over MOX. This is the largest federal construction project in the nation right now,” Jameson said. “The answer was no. She [National Nuclear Administration Principal Deputy Administrator Madelyn Creedon ]said they left it out on purpose, that they’re trying to get rid of it so they weren’t going to talk about it.”

to box up the project and move to another method of plutonium disposal known as dilute and dispose.

The NNSA has said the alternative is cheaper, citing life-cycle costs of MOX in the $50 billion to $60 billion range.

MOXAiken official: Savannah River Site’s MOX purposefully left out of NNSA discussion http://www.aikenstandard.com/article/20160914/AIK0101/160919745 Thomas Gardiner  Email  @TGardiner_AS  The speaker from the National Nuclear Security Administration at the Energy Communities Alliance meeting in Arlington, Virginia, this week intentionally snubbed the Mixed Oxide Fuel Fabrication Facility, or MOX, under construction at the Savannah River Site, one Aiken official said.

Due to its relation to the Site, Aiken has delegate members that make up the ECA, an organization of local governments adjacent to or affected by Department of Energy activities that meet to discuss issues, establish policy positions and promote community interests.

On Tuesday, Greater Aiken Chamber of Commerce President and CEO David Jameson and Aiken County Councilman Chuck Smith were both in attendance, where National Nuclear Administration Principal Deputy Administrator Madelyn Creedon addressed NNSA projects nationwide.

But Jameson said even with Smith, who is the current ECA chairman, seated just down the table from her, Creedon deliberately passed over the MOX project.

“The first question I asked was why if she mistakenly skipped over MOX. This is the largest federal construction project in the nation right now,” Jameson said. “The answer was no. She said they left it out on purpose, that they’re trying to get rid of it so they weren’t going to talk about it.”

Nearly $5 billion has been poured into the monolithic building thus far, setting the stage for ripe political debate.

Legislators that include U.S. Sens. Tim Scott, R-S.C., and Lindsey Graham, R-S.C., along with U.S. Rep. Joe Wilson, R-S.C., have battled the NNSA and the Obama administration, who have driven for months to box up the project and move to another method of plutonium disposal known as dilute and dispose.

The NNSA has said the alternative is cheaper, citing life-cycle costs of MOX in the $50 billion to $60 billion range.

U.S. Secretary of Energy Ernest Moniz mirrored Creedon’s presentation this week with his own comments at the Carnegie Endowment for International Peace.

Moniz said, “We are in no man’s land, where we spend enough money to not get anywhere. There is no way that Congress is going to commit to spending a billion dollars a year for half a century to dispose of 34 metric tons of plutonium.”

MOX is part of a plutonium disposal agreement with Russia inked in 2000. In the interest of non-proliferation, the two nations bilaterally agreed to destroy or disposition plutonium that would never again be usable in nuclear weapons.

According to Congressional testimony by Under Secretary for Nuclear Security and NNSA Administrator Retired Lt. Gen. Frank G. Klotz, USAF in May, the Obama administration wants to move away from MOX to the dilute and dispose method, which doesn’t change the physical properties or chemical makeup of the plutonium, without getting approval of the Russians

Reports in Russian media said President Vladimir Putin sees the move to dilute and dispose as being outside of the agreement.

Moniz responded to Russian complications at the Carnegie Endowment.

“We do have a few other issues to deal with Russia at this time, and it’s maybe not the most (favorable) time for that question, as President Putin has pointed out,” he said.

Meanwhile, Congress is currently funding MOX at about $350 million a year, which, according to the NNSA, is enough to keep the construction going, even if it is at a trickle. Funding for 2017 is not yet official but is included in all versions of the National Defense Authorization Act bill for the year. That bill is in inter-chamber conference, and legislators are hopeful it will be brought to the floor next week.

The NNSA has said the alternative is cheaper, citing life-cycle costs of MOX in the $50 billion to $60 billion range.

Life-cycle costs, however, are estimates from the time ground is broken until the mission is completed and the building’s purpose has been fulfilled entirely. Those costs can change drastically over time, especially considering what Jameson called the “slow-build” approach.

“I like to look at it this way,” Jameson said. “My wife and I were married 39 years ago. I know about how much our bills are, like mortgage payments, electricity, car payments and so on. Our wedding cost about $4,000 then, but would you ever say that the life-cycle cost of our wedding was $1.2 million?”

Britain’s national disgrace: nuclear reprocessing at Sellafield

The National Audit Office (NAO) stated these tanks pose “significant risks to people and the
environment”. One official review published in The Lancet concluded that, at worst, an explosive release from the tanks could kill two million Britons and require the evacuation of an area reaching from Glasgow to Liverpool. These dangerous tanks have also been the subject of repeated complaints from Ireland and Norway who fear their countries could be contaminated if explosions or fires were to occur.

In short, the practice of reprocessing at Sellafield has been and remains a monumental national disgrace.

Sellafield-reprocessing

Especially serious are the ~20 large holding tanks at Sellafield containing thousands of litres of extremely radiotoxic fission products. Discussing these tanks, the previous management consortium Nuclear Management Partners stated in 2012:

“there is a mass of very hazardous [nuclear] waste onsite in storage conditions that are extraordinarily vulnerable, and in facilities that are well past their designated life.”

most of all, we should recognize that nuclear policies, in both weapons and energy, have poorly served the nation.


sellafield-2011Sellafield exposed: the nonsense of nuclear fuel reprocessing
 
http://www.theecologist.org/reviews/2988095/sellafield_exposed_the_nonsense_of_nuclear_fuel_reprocessing.html  Ian Fairlie  6th September 2016   Last night’s BBC Panorama programme did a good job at lifting the lid on Britain’s ongoing nuclear disaster that is Sellafield, writes Ian Fairlie. But it failed to expose the full scandal of the UK’s ‘reprocessing’ of spent fuel into 50 tonnes of plutonium, enough to build 20,000 nuclear bombs – while leaving £100s of billions of maintenance and cleanup costs to future generations.

Many readers will have seen the interesting Panorama programme on the poor safety record at Sellafield broadcast on BBC1 last night.

The BBC press release stated this was a “special investigation into the shocking state of Britain’s most hazardous nuclear plant” – and it certainly was.

The most important of several whistleblower revelations was that the previous US managers had been shocked at the state of the plant when they took over its running in 2008.

Although the programme producers are to be congratulated for tackling the subject, it was only 30 minutes long and tells only a fragment of the whole sorry story.

This article tries to give more background information, and importantly, more analysis and explanation. The full story would require several books, and provide exceedingly painful reading.

The end of the line for Japan’s super expensive nuclear reprocessing project?

Monju has drifted on for years after its future was clearly in doubt. A decision now to terminate the project seems sensible. Such a decision should also prompt the government to stop and consider whether its nuclear fuel cycle still makes sense.

fast-breeder-Monju


flag-japanMonju and the nuclear fuel cycle
 http://www.japantimes.co.jp/opinion/2016/09/04/editorials/monju-nuclear-fuel-cycle/#.V8yFTFt97Gg Media reports that the government is finally weighing whether to pull the plug on the Monju fast-breeder reactor in Tsuruga, Fukui Prefecture, due to the massive cost needed to restart the long-dormant facility, should come as no surprise. Once touted as a “dream reactor” for an energy-scarce country that produces more plutonium than it consumes as fuel, Monju has been a nightmare for national nuclear power policy for the past two decades.

The sole prototype reactor for this kind of technology has been in operation a mere 250 days since it first reached criticality in 1994. It has mostly been offline since a 1995 sodium coolant leak and fire. Its government-backed operator has been declared unfit by nuclear power regulators to run the trouble-prone reactor, and the education and science ministry, in charge of the project, has not been able to find a viable solution.

More than ¥1 trillion in taxpayer money has so far been spent on Monju, and maintenance alone costs ¥20 billion a year. Restarting the reactor under the Nuclear Regulation Authority’s new safety standards would cost another several hundred billion yen, including the expense of replacing its long-unused fuel as well as its aging components — though there would still be no guarantee that it would complete its mission of commercializing fast-breeder reactor technology.

The Abe administration may think that writing off the ill-fated costly project, even with the projected ¥300 billion cost of decommissioning the facility over 30 years, will help win more public support for its policy of seeking to reactivate the nation’s conventional reactors — most of which remain idled in the wake of the 2011 meltdowns at Tokyo Electric Power’s Fukushima No. 1 plant — once they’ve cleared the NRA screening. Public concerns over the safety of nuclear energy remain strong after the Fukushima disaster, with media surveys showing a large portion of respondents still opposed putting the idled reactors back online.

If it is going to decide to decommission the Monju reactor, however, the government should also rethink its pursuit of the nuclear fuel cycle — in which spent fuel from nuclear power plants is reprocessed to extract plutonium for reuse as fuel. Monju, which runs on plutonium-uranium mixed oxide (MOX) fuel, has been a core component of the program. As Monju remained dormant for more than 20 years, the government and power companies have shifted the focus of the policy to using MOX fuel at regular nuclear power plants. The No. 3 reactor at Shikoku Electric Power’s Ikata plant in Ehime Prefecture, which resumed operation in August, runs on MOX fuel. The government apparently thinks the Monju program is no longer essential to the policy.

But the nuclear fuel cycle itself has proven elusive, and some say the policy has already collapsed. It is still nowhere in sight when the nuclear fuel reprocessing plant in Rokkasho, Aomori Prefecture — another key component in the program and whose construction began in 1993 — will be ready for operation.

After its scheduled completion in 1997 has been delayed by more than 20 times due to a series of technical glitches and other problems, its construction cost has ballooned three times the original projection to ¥2.2 trillion.

If indeed the Rokkasho facility is completed and starts reprocessing spent fuel from power plants across the country, the Ikata power plant is currently the only one in operation that consumes plutonium-uranium fuel. It’s not clear how many more will be up and running in the years ahead given the slow pace of restarting the idled reactors, and the Rokkasho facility operating without a sufficient number of reactors using MOX fuel would only add to Japan’s stockpile of unused plutonium — which has already hit 48 tons.

If it’s the cost problem that’s finally spelling doom for the Monju project, the government and power companies should also consider the cost-efficiency of the nuclear fuel cycle program, including the extra cost of reprocessing spent fuel into MOX fuel. They should also think about whether the program is compatible with the government’s stated policy — though its commitment may be in doubt — of seeking to reduce Japan’s dependency on nuclear power as an energy source.

Monju has drifted on for years after its future was clearly in doubt. A decision now to terminate the project seems sensible. Such a decision should also prompt the government to stop and consider whether its nuclear fuel cycle still makes sense.

Global nuclear industry ponders ways to get taxpayers to pay up for Small Modular Nuclear Reactors (SMRs)

text-cat-question

 

Doncha love the way they leave the word “nuclear” out of “SMRs”, hoping that people somehow won’t notice that SMRs are nuclear reactors?

Can SMRs unlock financing? World Nuclear news,  24 August 2016 Whilst a project of the size and complexity
of Hinkley Point C faces a range of challenges which lessen the availability of limited-recourse financing, it is clear that nuclear plant construction violates the basic precepts of project finance due to the unpredictability of project costs and schedule, write Rory Connor and Ken Culotta of law firm King & Spalding…..

For the industry to flourish, even in the presence of strong government policy support, the ability to finance is critical. There is the possibility though that new technology and new construction techniques, in the form of small modular reactors (SMRs), may hold the key to overcoming such issues……..

……..a long-term, minimum-price, power purchase agreement (or equivalent) a fundamental bankability requirement.

fleecing-taxpayer

The UK government’s Electricity Market Reform initiatives, including the flagship contract-for-difference, have shored up the bankability of nuclear power projects. However, in a controversial field like nuclear power, there remains a risk that political or public sentiment could change during the life a project; as happened in Germany, which effectively ended its nuclear power industry in the wake of the Fukushima disaster. Lenders will require assurances that changes in policy will not adversely affect their exposure. For Hinkley Point C, the UK government agreed to enter into a so-called Secretary of State Agreement with the project sponsors, which grants the sponsors a put-option against the government in the event of a political shutdown of the project, effectively requiring the government to compensate the sponsors for their loss of investment – project lenders would no doubt expect similar protection to cover the cost of repayment of all outstanding project debt.

Nevertheless, not even the package of the Hinkley Point C contract-for-difference (which guarantees a power price of more than double the prevailing market price over a 35-year term) and the Secretary of State Agreement was enough to satisfy prospective lenders or bond underwriters that the project represented a bankable proposal. The problem lurked elsewhere – construction risk……..

The first SMRs to be installed will doubtless surface interesting risk issues, particularly the perceived ‘new technology’ risk which would likely see lenders requiring extended warranties from SMR technology providers. …..

construction risk alone is not the only issue that makes project financing a challenge for nuclear projects – the highly regulated nature of nuclear power does not sit easily with many standard project financing instruments and techniques. In any event, the developer(s) of the first commercially deployed SMRs may decide to finance on-balance sheet or by other means.

But the fact is that SMRs are no longer just ‘pie in the sky’ – billions of dollars of investment has been committed to the development of this technology (including more than $200 million by the US Department of Energy and up to £250 million by the UK government) and, in the UK at least, the possibility of contracts-for-difference, and other government-backed credit enhancements, create an attractive framework for investment and financing.  http://www.world-nuclear-news.org/V-Can-SMRs-unlock-financing-24081602.html

Secretive manouvres involve tax-payer funds for Bill Gates’ small nuclear reactors

months have elapsed since the Microsoft Corp. co-founder and 27 other billionaires rolled out their Breakthrough Energy Coalition (BEC) — a promise to invest billions of dollars with a very long payback horizon on groundbreaking new carbon-neutral technologies. And the group has barely been heard from since.

Jonah Goldman, a spokesman for the coalition, said much of the work is happening behind the scenes.

Gates brought his message to Capitol Hill, where he met twice with Sen. Lamar Alexander (R-Tenn.) in the past year to press the Energy and Water Appropriations Subcommittee chairman for federal support for research and development.

The two men discussed small modular nuclear reactors and carbon capture and storage technology at the meetings, an Alexander aide said.

Gates'-travelling-Wave-Nucl

Nineteen countries joined the United States in backing Mission Innovation in Paris, and the European Union signed on in June. Since then, the Obama administration has followed up with a fiscal 2017 funding request of $7.7 billion for clean energy R&D across the federal government, with $5.9 billion of that going to DOE programs

What’s happening with Bill Gates’ multibillion-dollar energy fund? EENews, Jean Chemnick, E&E reporter, ClimateWire: Monday, August 15, 2016 Bill Gates believes the key to addressing climate change is an “energy miracle,” and in November, he set about trying to conjure one.

Flanked by President Obama and more than a dozen other world leaders in Paris for the first day of a landmark climate summit, Gates claimed a role for the private sector in delivering new solutions.

“We must … add the skills and resources of leading investors with experience in driving innovation from the lab to the marketplace,” Gates said that morning. “The private sector knows how to build companies, evaluate the potential for Breakthrough Energy Coalitionsuccess, and take the risks that lead to taking innovative ideas and bringing them to the world.”

But months have elapsed since the Microsoft Corp. co-founder and 27 other billionaires rolled out their Breakthrough Energy Coalition (BEC) — a promise to invest billions of dollars with a very long payback horizon on groundbreaking new carbon-neutral technologies. And the group has barely been heard from since.

Jonah Goldman, a spokesman for the coalition, said much of the work is happening behind the scenes. The fund, he said, will make announcements about the kinds of investments that will be made when it is up and running, likely toward the end of this year.

“But the focus is definitely more on doing the work we’ve committed to than making public pronouncements,” he said.

A few things are clear. Some of the group’s contributions will flow through a fund that will concentrate on certain kinds of investments. The group is currently hiring scientists and investment professionals who will direct those decisions. Goldman declined to say how many people are working to stand up the fund or how many employees it will eventually have.

Other things remain a mystery, including the coalition’s eventual capitalization target. Gates promised to invest an additional $1 billion of his own dollars when he launched BEC, and predicted the other members would contribute a collective “couple” billion more toward the venture. But it is unclear how much of that $3 billion — if it is $3 billion — will flow through the fund, versus members investing it independently. Goldman said the total size of the fund and targets for investment will be based on this year’s fundraising.

He said the goal would be to raise a level of capital that the fund could deploy effectively, with the understanding that some of the group’s members will continue to invest in projects outside the fund.

“We feel tremendously confident that we will get significant participation in the ultimate funding vehicle, but each of the potential investors will have to make that decision based on the terms presented, and we’re not quite there yet,” he said…..

Gates brought his message to Capitol Hill, where he met twice with Sen. Lamar Alexander (R-Tenn.) in the past year to press the Energy and Water Appropriations Subcommittee chairman for federal support for research and development.

The two men discussed small modular nuclear reactors and carbon capture and storage technology at the meetings, an Alexander aide said.

Then, in the three months before Paris, Gates bore down. He joined Energy and State department officials and White House personnel on calls with foreign governments to urge them to sign on to Mission Innovation, a commitment by countries to double their individual R&D budgets by 2020. Energy Secretary Ernest Moniz spearheaded the initiative, which was unveiled in Paris alongside BEC (EnergyWire, Dec. 17, 2015).

On those calls, former officials say Gates offered the private investors fund as a kind of carrot, promising to help carry technologies produced in national laboratories across the “valley of death” — where ideas often perish for lack of investment — toward greater development that leads to commercialization.

But first governments had to put up the money…….

DOE vague on BEC relationship

Nineteen countries joined the United States in backing Mission Innovation in Paris, and the European Union signed on in June. Since then, the Obama administration has followed up with a fiscal 2017 funding request of $7.7 billion for clean energy R&D across the federal government, with $5.9 billion of that going to DOE programs…….

DOE was less forthcoming about its work with BEC post-Paris. A department spokesman said in response to an inquiry only that the agency “is in communication with thousands of researchers, entrepreneurs, inventors, small businesses and large corporations.”

While the spokesman asserted that the investors’ group and Mission Innovation are “separate” and “complementary,” the private-sector group has popped up in DOE communications with interested members of civil society. It figured, for example, in a slideshow presentation that Office of International Science and Technology Collaboration Director Robert Marlay prepared for the U.S. Energy Information Administration earlier this year.

The presentation states that the fund would provide “seed, angel and series A” investments. Seed capital is offered in exchange for a stake in a company, while angel investments help startup companies. “Series A” investments are typically the first round of venture capital investments that are made in a new company….

Some of the Gates group’s radio silence appears to be strategic.

Bodnar said Gates and his partners opted not to put forward a concrete pledge of dollars in Paris because it wasn’t a venue where the contribution would appear in its best light. Even a funding target that would be enough to fulfill the group’s goal of readying promising technologies for the market would pale in comparison to the hundreds of billions or even trillions of dollars that are routinely discussed in the multilateral climate process…..

what the 28 billionaires managed to do was to signal there will now be “truly patient, flexible” capital available for promising technologies that make it through the basic research phase. Patient capital is seen to be key, because the high risk and very long time horizons for payback have generally made these technologies unattractive to conventional investors.

Bodnar said Gates and his colleagues were confident that the money they put up would be sufficient to ensure the gap is bridged between federally funded basic research and ready-to-deploy commercial technologies……http://www.eenews.net/stories/1060041571

With Hinkley Big Nuclear in decline, the “Small Nuclear” lobby sees its chance

Don’t worry: British nuclear doesn’t have all its eggs in one basket, Weinberg Foundation August 11th, 2016 by Suzanna Hinson
Small nuclear salesman

Hinkley Point may be taking all the attention at present, but it is not the be all and end all of nuclear power in the UK. There is plenty more in the pipeline so, whatever happens in Somerset, progress can be made elsewhere. The UK’s Office for Nuclear Regulation aims to complete Generic Design Assessments for new reactors, the AP1000 and Advanced Boiling Water Reactor (ABWR), during 2017.

NuGen, jointly owned by Japan’s Toshiba and France’s Engie, is progressing with plans to build an AP1000 at Moorside in West Cumbria. At present, they are carrying out site assessment surveys, including geophysical surveys, geological age dating and some borehole drilling work, which must be completed before construction can begin. AP1000 reactors, designed by Westinghouse, are being planned in multiple countries worldwide, with the first plants scheduled to come online in China this year. There have been some delays on these world-first reactors, but not as serious as those in France and Finland for the European Pressurised Reactor (EPR) proposed for Hinkley…….

In addition to these planned sites, there is also ongoing research and development into the next generation of advanced nuclear reactors. The Government promised, in Autumn 2015, an investment of £250 million over 5 years to develop the reactors of the future. This includes a competition to decide which small modular reactor or reactors should be demonstrated in the UK. Advanced reactors have the potential to be cheaper, even cleaner and even safer than current designs, and have added benefits such as the potential ability to use up spent fuel and the plutonium stockpile. (Weinberg Next Nuclear will soon be publishing a report on how to manage plutonium)….http://www.the-weinberg-foundation.org/2016/08/11/dont-worry-british-nuclear-doesnt-have-all-its-eggs-in-one-basket/

The tiresome ‘Thor-Bores” – exploding the hype about thorium nuclear reactors

Thorium-cultThorium: new and improved nuclear energy? https://www.wiseinternational.org/nuclear-energy/thorium-new-and-improved-nuclear-energy

There is quite some – sometimes tiresome – rhetoric of thorium enthusiasts. Let’s call them thor-bores. Their arguments have little merit but they refuse to go away.

Here are some facts:

  • There is no “thorium reactor.” There is a proposal to use thorium as a fuel in various reactor designs including light-water reactors–as well as fast breeder reactors.
  • You still need uranium – or even plutonium – in a reactor using thorium. Thorium is not a fissile material and cannot either start or sustain a chain reaction. Therefore, a reactor using thorium would also need either enriched uranium or plutonium to initiate the chain reaction and sustain it until enough of the thorium has converted to fissile uranium (U-233) to sustain it.
  • Using plutonium sets up proliferation risks. To make a “thorium reactor” work, one must (a) mix the thorium with plutonium that has been stripped of the highly radioactive fission products; (b) use the mixed-oxide thorium-plutonium fuel in a reactor, whereby the plutonium atoms fission and produce power while the thorium atoms absorb neutrons and are turned into uranium-233 (a man-made isotope of uranium that has never existed in nature); (c) strip the fission products from the uranium-233 and mix THAT with thorium in order to continue the “cycle”. In this phase, the U-233 atoms fission and produce power while the thorium atoms absorb neutrons and generate MORE uranium-233. And so the cycle continues, generating more and more fission product wastes.
  • Uranium-233 is also excellent weapons-grade material. Unlike any other type of uranium fuel, uranium-233 is 100 percent enriched from the outset and thus is an excellent weapons-grade material and as effective as plutonium-239 for making nuclear bombs. This makes it very proliferation-prone and a tempting target for theft by criminal and terrorist organizations and for use by national governments in creating nuclear weapons.
  • Proliferation risks are not negated by thorium mixed with U-238. It has been claimed that thorium fuel cycles with reprocessing would be much less of a proliferation risk because the thorium can be mixed with uranium-238. In fact, fissile uranium-233 must first be mixed with non-fissile uranium-238. If the U-238 content is high enough, it is claimed that the mixture cannot be used to  make bombs with out uranium enrichment. However, while more U-238 does dilute the U-233, it also results in the production of more plutonium-239, so the proliferation problem remains.
  • Thorium would trigger a resumption of reprocessing in the US. In most proposed thorium fuel cycles, reprocessing is required to separate out the U-233 for use in fresh fuel. Reprocessing chemically separates plutonium and uranium and creates a large amount of so-called low-level but still highly radioactive liquid, gaseous and solid wastes.
  • Using thorium does not eliminate the problem of long-lived radioactive waste. Fission of thorium creates long-lived fission products including technetium-99 (half-life of over 200,000 years). Without reprocessing, thorium-232 is itself extremely long-lived (half-life of 14 billion years) and its decay products will build up over time in irradiated fuel. Therefore, in addition to all the fission products produced, the irradiated fuel is also quite radiotoxic. Wastes that pose long-term hazards are also produced at the “front end” of the thorium fuel cycle during mining, just as with the uranium fuel cycle.
  • Attempts to develop “thorium reactors” have failed for decades. No commercial “thoriumreactor” exists anywhere in the world. India has been attempting, without success, to develop a thorium breeder fuel cycle for decades. Other countries including the US and Russia have researched the development of thorium fuel for more than half a century without overcoming technical complications.
  • Fabricating “thorium fuel” is dangerous to health.  The process involves the production of U-232 which is extremely radioactive and very dangerous in small quantities. The inhalation of a unit of radioactivity of thorium-232 or thorium-228 produces a far higher dose than the inhalation of uranium containing the same amount of radioactivity. A single particle in the lung would exceed legal radiation standards for the general public.
  • Fabricating “thorium fuel” is expensive. The thorium fuel cycle would be more expensive than the uranium fuel cycle. Using a traditional light-water (once-through) reactor, thorium fuel would need both uranium enrichment (or plutonium separation) and thorium target rod production. Using a breeder reactor makes costly reprocessing necessary.
The bottom line is this.Thorium reactors still produce high-level radioactive waste. They still pose problems and opportunities for the proliferation of nuclear weapons. They still present opportunities for catastrophic accident scenarios–as potential targets of terrorist or military attack, for example. Proponents of thorium reactors argue that all of these risks are somewhat reduced in comparison with the conventional plutonium breeder concept. Whether this is true or not, the fundamental problems associated with nuclear power have by no means been eliminated.

Are tax-payers paying for nutty space nuclear research?

BRINGING NUCLEAR POWER TO MARS – FRANK H. SHU (SETI TALKS 2016), Raw Science  SETI Talks @ MicroSoft Silicon Valley – July 29, 2016 Dr. Frank Shu lectured with SETI Talks at MicroSoft Silicon Valley on July 29, 2016:

spacecradt-plutonium-

Establishing a lunar base is probably a wise first first step to colonizing Mars, and colonizing Mars will be a giant leap forward for humankind to travel to the stars…..

A reliable source of primary energy is needed for such tasks, but anywhere on the surface of the Moon, there is no sunlight two weeks out of four, and no wind whatsoever. Nuclear power is the default option, just as is the case of naval submarines where the crews need to live and work in closed environments submerged under the water of the ocean for months at a time. However, the light water reactors of naval submarines are not a good choice for environments that lack large bodies of water, and we argue, as first realized by a former NASA Engineer, Kirk Sorensen, that molten salt reactors, of the type invented by Oak Ridge National Lab in the 1960s, are much better suited for a lunar base, or for that matter, a Mars colony.

Dr. Shu discussed his patented design for the best possible two-fluid molten-salt breeder-reactor (2F-MSBR) that one could build, using thorium that can be mined locally without requiring shipments from mother Earth. He closed by considering two spin-off applications:
(1) saving civilization on Earth from the worst ravages of climate change by scaled-up 2F-MSBRs;
(2) using the fission fragments of related nuclear fission reactions for ion-propulsion that produces rockets two to three orders of magnitude faster than achievable with chemical rockets, making possible, perhaps, a first generation of starships. http://www.rawscience.tv/bringing-nuclear-power-to-mars-frank-h-shu-seti-talks-2016/

UK govt accidentally published list of preferred bidders for funding for Small Modular Nuclear Reactors

Emperor's New Clothes 3flag-UKChinese firm with military ties invited to bid for role in UK’s nuclear future
China National Nuclear Corporation on government list of preferred bidders for development funding for next-generation modular reactors,
Guardian, , 8 Aug 16“……….The list of companies accepted for the competition was published briefly, apparently accidentally, on the website of the new Department for Business, Energy and Industrial Strategy on Friday before being deleted. It reads as a who’s-who of US, British, Japanese and Chinese industry players hoping to develop and build small modular reactors. These are much smaller than conventional nuclear plants with a capacity of less than 300MW – or a 10th of what Hinkley Point C should provide.

They are pitched by industry as a cheaper and quicker way to provide low-carbon energy capacity than conventional big nuclear plants because they could be built in a factory and transported to where their power is needed. The US and UK are racing to be the most attractive home for the first of the new designs to be commissioned.

Last November, George Osbornepromised £250m over five years for a nuclear research and development programme to “revive the UK’s nuclear expertise and position the UK as a global leader in innovative nuclear technologies”. An undisclosed amount of that sum is for a competition to find the best value SMR design for the UK, to “pave the way” towards building one in the UK in the 2020s.

CNNC sits alongside US companies such as NuScale; British ones including Rolls-Royce, Sheffield Forgemasters and Tokamak Energy; Japanese-owned Westinghouse; and the US-Japanese partnership GE-Hitachi, as participants the government considers eligible for phase one of its competition.

CNNC’s chief designer of small nuclear plants visited a conference in London last year to pitch a plan for cooperating with UK industry, and is already partnering with Rolls-Royce. It hopes to build the first SMR in the UK, with future ones sold around the world.

NuScale Power put itself forward for the competition in the spring. Its design, said its managing director, Tom Mundy, “answers the particular needs of the UK’s energy market and the wider UK economy, and we intend to participate fully in the government’s competition”.

The 33 participants will be whittled down in several phases, with the announcement of the eventual winners scheduled for late 2017……

When asked about the list published on Friday, a spokeswoman for the Department of Business, Energy and Industrial Strategy, said: “In March 2016, the government launched the first phase of a competition to identify the best value SMR for the UK. The ambition is to create an opportunity for the UK to become a world leader in SMRs.

“Those companies which are eligible to participate in the competition have been aware for over two months.”  https://www.theguardian.com/environment/2016/aug/07/chinese-firm-with-military-ties-invited-to-bid-for-role-in-uks-nuclear-future

Integral Fast Reactors (IFRs) NOT the nuclear solution that its fans claim it to be

IFR-lemonNuClear News August 16  Integral Fast Reactors (IFRs) George Monbiot told the Radio 4’s Today Programme on the 29th July that the “humungous waste problem at Sellafield could be turned into a humungous asset by using a technology such as Integral Fast Reactors (IFR) to turn it into an energy source.” He said “it gets rid of the waste, and according to one estimate could provide all the UK’s energy needs for 500 years.” He said that instead of wasting our money on Hinkley Point C Government should invest in the development of IFRs to “see if we can use it to crack two problems at once – our nuclear waste mountain [and] create a massive source of low carbon energy”. The only problem is, as Professor Catherine Mitchell just had time to point out, it wouldn’t work. To claim that they are proliferation resistant and help “use up waste” is just plain wrong.

 

The IFR would be a liquid-sodium-cooled fast-neutron reactor. The use of liquid sodium as a coolant has proved to be a huge problem in the past – it catches fire on contact with air. Over the years the world’s leading nuclear technologists have built about three dozen sodium-cooled fast reactors. Of the 22 whose histories are mostly reported, over half had sodium leaks, four suffered fuel damage (including two partial meltdowns), several others had serious accidents, most were prematurely closed, and only six succeeded. As Dr. Tom Cochran of NRDC notes, fast reactor programs were tried in the US, UK, France, Germany, Italy, Japan, the USSR, and the US and Soviet Navies. All failed. After a half-century and tens of billions of dollars, the world has one operational commercial-sized fast reactor (Russia’s BN600) out of 438 commercial power reactors, and it’s not fuelled with plutonium.

 

 

IFRs would require an ambitious new nuclear fuel cycle because they would be fuelled with a metallic alloy of uranium and plutonium. In theory they would operate in conjunction with onsite ‘pyroprocessing’ to separate plutonium and other long-lived radioisotopes. Unlike the reprocessing plants currently at Sellafield they wouldn’t separate pure plutonium, but would keep the plutonium mixed with other long-lived radioisotopes.

 

Its novel technology, replacing solvents and aqueous chemistry of current reprocessing with high-temperature pyrometallurgy and electrorefining, would incur different but major challenges, greater technical risks and repair problems, and speculative but probably worse economics. Reprocessing of any kind makes waste management more difficult and complex, increases the volume and diversity of waste streams, increases by several- to many-fold the cost of nuclear fuelling, and separates bomb-usable material that can’t be adequately measured or protected. In the UK the Government would be unlikely to want to see more plutonium separated so any IFR built here – at least to begin with – would probably just be used to use up our huge stockpile of plutonium. The problem is that the plutonium is stored as plutonium oxide which would have to be converted to plutonium metal probably involving the fluorination of plutonium dioxide, normally with highly corrosive hydrogen fluoride, to produce plutonium fluoride, which is subsequently reduced using high purity calcium metal to produce metallic plutonium and a calcium fluoride slag.

 

 

IFRs are often claimed to “burn up nuclear waste” and make its “time of concern … less than 500 years” rather than 10,000-100,000 years or more. That’s wrong: most of the radioactivity comes from fission products, including very long lived isotopes like iodine-129 and technicium-99, and their mix is broadly similar in any nuclear fuel cycle.

 

IFRs’ wastes may contain less transuranics, but at prohibitive cost and with worse occupational exposures, routine releases, accident and terrorism risks, proliferation, and disposal needs for intermediate- and low-level wastes. It’s simply a dishonest fantasy to claim, that such hypothetical and uneconomic proposals can deal with the humungous waste problem at Sellafield.

 

 

It is claimed that IFRs could produce lots of greenhouse-friendly energy and while they’re at it they can ‘eat’ nuclear waste and convert fissile materials, which might otherwise find their way into nuclear weapons, into useful energy. Too good to be true? Sadly, yes. Nuclear engineer Dave Lochbaum from the Union of Concerned Scientists writes: “The IFR looks good on paper. So good, in fact, that we should leave it on paper. For it only gets ugly in moving from blueprint to backyard.”http://www.no2nuclearpower.org.uk/nuclearnews/NuClearNewsNo87.pdf

With UK and USA government help, NuScale hopes to go ahead with “mini” nuclear reactors

NuClear News No 87, 5 Aug 16 Small Modular Reactors (SMRs) Britain’s ambition to build small modular nuclear plants took a step forward as the nation’s last independent steelmaker said it will work with Fluor Corp.’s NuScale Power to make components. Sheffield Forgemasters International Ltd. will forge a large civil nuclear reactor vessel head by the end of 2017. It is part of a £4m programme funded by the government-backed Innovate U.K. agency. NuScale is providing an undisclosed sum of additional funding.
In the USA, NuScale says it is “at an advanced stage” of development compared to its nearest competitors. NuScale is the only SMR developer to be currently receiving US Department of Energy match funding ($217 million over five years), the only SMR developer to be close to submitting a Design Certification Application to the US Nuclear Regulatory Commission – which NuScale says will happen later this year – and it has “multiple active customer deployment projects under way”. The first NuScale facility is planned to be in operation in 2024 in the state of Idaho. (2)
New “mini” nuclear reactor technology should be built at Trawsfynydd – the site of a closed Magnox station – according to the Welsh Affairs Select Committee. The nuclear plant in Snowdonia National Park has been shut down since 1991 and is undergoing the lengthy process of decommissioning. The Welsh Affairs select committee said the site would make an “ideal” location to build small modular reactors, and urged the Government to designate it as a site for their construction. Trawsfynydd was not included on the list of approved sites for new nuclear construction drawn up by the Government in 2009, due to its inland, national park location and small size. But there is growing support in Wales for the idea that it could be suitable for small module reactor (SMR) technology, which is by definition smaller and proponents say will be much easier to construct.
NuScale Power has become a supporting partner of the Nuclear Advanced Manufacturing Research Centre (Nuclear AMRC) in Sheffield. The two bodies said the move, which follows several years of informal collaboration, will further enable the two organisations to support each other’s ambitions to bring SMR technology to the UK. The announcement was made on the same day that Nuclear AMRC hosted NuScale Power’s first UK Supplier Day at its facility at the University of Sheffield.

NASA to send nuclear powered spacecraft to Mars (hope it doesn’t crash)

spacecradt-plutonium-NASA books nuclear-certified Atlas 5 rocket for Mars 2020 rover launch, Spacefilght Now, July 25, 2016 Justin Ray CAPE CANAVERAL — America’s next Mars rover, a $2.1 billion nuclear-powered vehicle to search for evidence that life once existed there, will be launched to the Red Planet in the summer of 2020 by a powerful Atlas 5 rocket.

Jim Green, planetary science division director, revealed the selection of the United Launch Alliance vehicle at the NASA Advisory Council meeting in Cleveland this afternoon.

“It will be the Atlas 5 carrying Mars 2020 to Mars,” Green said.

ULA’s Atlas 5 and Delta 4-Heavy and SpaceX’s Falcon Heavy were studied as possible launch vehicles for the intermediate-to-heavy classed payload. It was not immediately known if SpaceX submitted a bid for this launch contract.

But, currently, Atlas 5 is the only launch vehicle that holds a NASA certification for launching the nuclear batteries made of plutonium that will power the 2,000-pound rover.

The six-wheeled robot will use by a Multi-Mission Radioisotope Thermoelectric Generator, enabling surface operations day and night by converting heat into electricity.

Atlas 5 has successfully performed the only launches of nuclear-equipped spacecraft for NASA in recent history: New Horizons to Pluto in 2006 and the Mars Science Laboratory’s Curiosity rover in 2011.

The Mars 2020 mission will search for indications of past Martian life, building upon the ongoing field geology work by the Curiosity rover that shows the planet’s early history had conditions suitable for life…….https://spaceflightnow.com/2016/07/25/nasa-books-nuclear-certified-atlas-5-rocket-for-mars-2020-rover-launch/
